High sensitivity C-reactive protein (hs-CRP) is a marker of low-grade sustained inflammation.

Omega-3 (n-3) fatty acids have anti-inflammatory properties and are associated with reduced cardiovascular disease (CVD) risk.

The aim of this study was to investigate whether plasma n-3 fatty acid concentration is related to hs-CRP concentration.

A total of 124 free-living adults were divided into tertiles [three groups] of plasma hs-CRP (3.0 mg/l). Body composition and anthropometric measurements were recorded. Hs-CRP was analyzed using immunoassays and fatty acids were measured by gas chromatography.

Plasma hs-CRP concentration was negatively correlated with total n-3 fatty acids (P=0.05), eicosapentaenoic acid (EPA; P=0.002) and docosapentaenoic acid (DPA; P=0.01).

The highest hs-CRP tertile (>3.0 mg/l) had significantly lower concentrations of total n-3 fatty acids, EPA and DPA, when compared with the other tertiles (P<0.05).

This study provides evidence that in healthy individuals, plasma omega-3 fatty acid concentration is inversely related to high sensitivity C-reactive protein concentration, a surrogate marker of cardiovascular disease risk. [Higher omega-3, lower hs-CRP]

    It is not surprising to learn that those with higher levels of omega-3 fatty acids had lower levels of C-reactive protein. I am curious whether the subjects provided any other information about their health status that would indicate some manifestation of this low-grade inflammation, such as pain, digestive problems, emotional difficulties or subtle signs of heart disease, such as a tendency towards higher blood pressure compared to the other group.
